METALLIC WINDOW-SLIDE.

SPEGIFICATION forming pa.rt of Letters Patent N0. 579,631, dated March30, 1897. Application filed January 20, 1896. Serial N0. 576,183. (N0model.)

T0 all wh0m z'25 may c0ncern:

Bc it known that I, WILLIAM ZUPPANN, a citiz cn of the Unitcd Staates,residing at farsaw, in thc county 0f Haneock ancl State 0f lllinois,have invented a ncw and useful Metallic VVindow-Slide, of Which thefollowing is a specification.

This invcntion relates to an improvcmcnt in metallic window-slicles f0rwindows, sereens, &c.; ancl tl1c objcet in view is 130 proviclc a simpleancl efficieht guiding strip o1 slide which may be usecl upon anywinclow, which wilhprotect the window-sashes from swelling and warping,and Which is constructecl in such manner that it may be easily andreaclily 1 cmovccl whenever it becom es ncccssary to takc out thewindow-sashes, screens, &c.

A further object of the invcntion is to con-' struct such slide in amanner that Will adapt it to receive and engage a spring-catch carrieclloy one o1 both of thc wincl0w-sashcs 01 tl1e scrcen-frames.

l/Vith Ehe above objects in view the invention consists in certain novelfcatures and details 0f construetion and arrangement 0f parts, ashcreinafter fully clescribed, illustrated in the drawings, andfinallypointcd out in the claims.

In the accompanying drawings, Figure 1 is a perspectivc view of asufficient portion of a window framc, sash, &c., to illustrate theapplication of the present improvement thereto. Fig. 2 is an enlargccldetail horizontal section through tl1c sa1ne. Fig. 3 is a detailvcrtical section through the window-sill and lower rail of a sash. Figs.4 to 8, inclusive, show different forms of slides. Fig. 9 is a detailperspcctive view showing the groovecl metal strip applied to the siderail of a window-sash.

Similar numerals of reference designate corresponding parts in tl1eseveral figures of the drawings.

Referring t0 tl1e accornpanying clrawings, 1 designates a window frame01 casing which for the purposes of thc presentinvention is left smoothupon its inner surfacc, the usual stops 01 guiclin g strips 01 beadsbeing omitted. In lieu of the usual wooden stops 01 beads I construct aspccial slirle, as inclicated at 2. This slide is formcd of sheetmaterial, preferably metal, in the form of strips corresponding inlength to the height and Width of tl1e window-casing. Bach strip isforrned at 01 adjacent to its central portion With a longi tudinal rib01 guide 3, forrned by bending 01 recurving oho metal upon itsclf atsuch point and extcnding the edge portions 4 at 1'ight angles to suchrilo po1t-ion and in alincment With each othe1. One 0f the edgeportions4 0f the strip 1's provided With a series 0f perforations 5 forthe reception of thc retainingscrews, and the remaining edge portionupon the opposite side of thc 1ib is formed With a scries of opentransverse slots 6, extending at rigbt an gles t0 saicl rib ancladaptccl to receivc theheads of other retaining-scrcws, as shown.

By folcling the mctal to forn1 the rib 3 and providing the open slots 6the said rib may expand and contract, and by reason of its elasticityWill yieldingly and snugly fit the grooves in the sash ancl prevent theSame fro1n rattling, ancl also compensate for wear between thc parts,while at the san1e time saicl slots willpermit thc slide to be removedsimply by looscning thc screws, as hereinaf ter clcscribed.

A numloer of perforations 01 sookets 7 a1e formed in o1 through thecentral longitudinal 1'ib 3, the san1e being adaptcd to receive theinwarclly-projecting extrcmity of a lock-pin 8, attachecl 130 a spring9, secured, preferably, to oho inner surface of onc of the side rails 0fthc sash, tl1e said spring bcing proviclccl With a button orfinger-grasp 10, whereloy the saicl spring may be clrawn away fron1 thesash ancl thc point of the pin removecl from engagemcnt With theperforations 01' sockets 7 in the slide.

The slides 0r strips above described are secured in the manner referreclto 130 thc inner surfaces of the sidcs, top, and sill ofanywindow-casing, and While the upper ancl lower slides are preferablymacle continuous or extencled in one piece the entire Width 0f thecasing the vertical strips 01 slides are preferably macle cach in twosections Which correspond to the height of the winclow-sashes, sucharrangement facilitating the removal of the slides and window-sashcswhen necessary. Each of the winclow-sashes, and the screenfran1es also,Wl1erc such are uscd, is fo1mcd with longitudinal grooves in the outeredges of its side, top, and bottom rails, the saicl groovcscorresponding t0 and adapted 130 fit IOO over anti slide upon tl1e ribs3, 01 the said grooves me made slightly lmger, so as t0 re ceive tl1eU-shaped 01' hollow rib 11 of a strip 12, secured to each of the sideedges of the sashes and t0 the top and bottom edges thereof, accordingas the sash is oho upper 01 lower ono. The use of the strip 12 preventsthe wetting of the edges of the sash and the cousequent swelling 0f thesame and the binding of the sashes within the fra1ne. This enablos thesashes so be moved easily up HDd Clown and renders it possible to makesuch a close-fitting engagement between the sashes and the window-framethat the weather will be effecoively excluded and all rattling of thesashes obviated.

When it is desirod so ren1 ove the sashes f01 any reason, they nmy be1noved upward, so as to expose oho lower retainingscrews passing throughthe perforations 5 of tl1e slicles. Such sorews are then removed, afl1erwhich oho positions 0f the sashes a1e reversed and the uppercorresponding screws removed. This will allow he sashes 120 be drawninward, an l oho slides 2 Will be clrawn out of engagement With tl1eouter retaining-screws, which hzwo thoir heads in engagement with theopen slots 6 desoribed. The sashes may be replaoed by reversing thisoperation.

In Fig. 5 I lmve shown how the slicles may bo macle in aslightly-clifferent fonn, in this case Ehe longitudinal rib 3 beinghollow am]. of reetangular cross-sectional shape. In this case also, inlieu 0f the perforations 7, notches 13 n1ay be formed in the rib f01i;he recepblon of l;he lockpin 8.

Figs. 6 anal 7 show, respectively, the rib 3, made in V sha-pe and in Ushape in crossseotiou. In will bo understood filmt in oho employmont ofeither of the modified fonns 0f llbS tho srip 12 will beoorresponclingly altorocl as t0 tl1e shape of its hollow 1ib, so as toaclapt it 130 fit over ancl slide upon the rib 3.

If dosired, instead of providing a separate and inependen sot of slidesfor each sash a single seo may be employed, the same being provided wiuhtwo 01 three 01' more ribs, as indicated in Fig. 8, according 130 thenun1ber 0f sashes 01 screen-frmnes employed.

II; will thus be seen that {L very simple, inexpensive, and efficienl;strip is obuained, which will effeotively exelude wind, min, &o., WhichWill admit of the ready removal of the sashes, and which Will, inconnecion with the spring-misch 011 each of oho window-sashes 01soreen-frames, enable tl1e latter to bo hold at any desired height. ItWill be appareni; thao the positions of. the strip 12 and slicle 2 maybe reversecl, the strip 12 being applied to.the window-fmme am]. theslide 2 to nhe sash; also, that any forn1 of sash-lock may be employedin connection with the improved strips or slides.

Changes in the forma, proportion, zu1d mi1101 details of constructionmay be resortecl t0 without depavting from 11110 spirit 01 saorificingany of the advantages 01": this invention.

IIaving thus described the invent-ion, what is claimed as new isl. Aslide f01 window-sashes, &o., eonsisting of a metal strip creasedlengthwise and folded upon it-self t0 form a longitudinal andlaterally-expansivo i'ib, one of the edge portions of the strip beingextended substantially a1; a, 1'ight angle to such rib and provided alsintervals with slots running at right angles 130 the rib am]. opening0ut ab the edge 0f the strip, wherebyuhe slide is ma le removable andthe rib allovvod to expand and contract, substantially as desoribed.

2. 'lhe herein-described slide, consisuing 0f 21 strip of sheeu metalcreased lengt-hwise ab different intervals between its side edges toform a series of longitudinal 1ibS f01 engaging uhe window-sashes undalso a screen-frame 01' blind, ll6 edge portions 0f the stripbeinglocatecl in the szune plane and one of said portions havinginclosed perforauions while the remaining portion is provicled With openslots extending ab righu angles t0 said 1ibs, substantially as and f01the purpose deseribed.

In testimony filmt I claim tl1e foregoing as my own I havehereto affixed1ny signature in ehe presence of tw0 witvnesses.
